B&M 20228 "Transpak" Shift Improver Kit
Fits 1965-1987 TH-400, 375 and M40

The B & M Transpak has all the features of B & M's Shift Improver kit plus it provides additional driver manual control. Now you can downshift at any speed, and you can hold the transmission in first gear for as long as you want to. This is ideal for drag racing or whenever you need the RPM for towing a trailer or hauling heavy loads on long grades. Two kits in one, choose the stage that best suits your needs.

Stage 1 is for normal passenger vehicles and will provide a firmer shift feel that is still not harsh. It will improve transmission life and performance without loss of comfort and retains normal operation when in "drive".

Stage 2 is the high performance street package. It provides much snappier shifts with full manual control but it still retains standard shift points when the selector is left in "drive".


A B&M Transpak Kit is not a repair kit for an ailing transmission.
Your transmission must be in top condition before installing this kit.
